Measuring Instrument Dynamic Scale Interval Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional dial gauges face challenges in balancing readability and measurement range, particularly when measuring small dimensions within tight tolerances, as the scale interval is often set uniformly across the entire range, making it difficult to read measurements within dimensional tolerances.
Innovation Solution
A measuring instrument utilizing an organic electroluminescent panel or electronic paper with a display controlling section that adjusts scale segment images based on input scale interval information, allowing for customizable scale intervals and improved readability within specified areas, including the option to input dimensional tolerances for precise measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wide scale interval is used, then the scales are easily read, but the measurement range becomes narrow
Solution Approach 1:
The patent applies dynamics by making the scale interval changeable rather than fixed. The display controlling section dynamically adjusts the scale interval based on the measurement range being used, allowing the instrument to optimize readability for the current measurement context while maintaining adaptability across different measurement ranges.
Solution Approach 2:
The patent changes the parameter of scale interval from a fixed value to a variable that can be adjusted based on measurement requirements. The scale information input section allows users to input different scale interval values, and the display controlling section applies these changes to display the appropriate scale interval for the current measurement range, thus resolving the contradiction between readability and measurement range.
2Adaptability or versatility
If a narrow scale interval is used, then the measurement range is enlarged, but the scales become difficult to read
Solution Approach 1:
The system dynamically adjusts the scale interval based on the measurement range being used. When measuring within a narrow tolerance range, the display controlling section increases the scale interval to improve readability. When measuring across a wide range, it reduces the scale interval to maintain measurement range coverage, thus resolving the contradiction dynamically.
Solution Approach 2:
The patent allows the scale interval parameter to be changed based on measurement requirements. The scale information input section enables input of different scale interval values, and the display controlling section applies the appropriate scale interval to optimize both measurement range and readability for the current measurement task.
3Adaptability or versatility
If a uniform scale interval is set across the entire measurement range, then the measurement range is covered, but readability within specific tolerance ranges is poor
Solution Approach 1:
The patent applies local quality by allowing different scale intervals to be applied to different measurement ranges. The scale information input section enables specification of scale intervals for specific display areas or measurement ranges, and the display controlling section applies the appropriate local scale interval settings. This allows optimization of readability within specific tolerance ranges while maintaining coverage of the entire measurement range.

AI summary
A measuring instrument includes a display on which measurements are displayed. The display is provided by an organic electroluminescent panel or an electronic paper including an assembly of organic electroluminescence devices and includes: a display controlling section that displays a plurality of scale segment images at an equal interval and a pointer image at a position corresponding to the measurements among display areas displayed by the plurality of scale segment images; and a scale information input section that specifies at least one of the display areas and inputs scale interval information of the scale segment images on the specified area. The display controlling section includes a scale interval changing section that, based on the scale interval information, displays the scale segment images on the specified area commanded by the scale information input section.
